4. The Main AC Power going to the C2200 and any other
McIntosh Component(s) should not be applied until all the
system components are connected together. When the
C2200 and other McIntosh Components are in their
Standby Power Off Mode, the Microprocessor’s Circuitry
inside each component is active and communication is
occurring between them. Failure to do so could result in
malfunctioning of some or all of the system’s normal
operations.
5. Up to four Sensors can be wired in parallel for Remote
Control of the C2200 from other rooms.
6. Balanced and Unbalanced Inputs and Outputs can be
mixed. For example, you may connect signal sources to
Unbalanced Inputs and send signals from the Balanced
Outputs. You can also use Balanced and Unbalanced
Outputs simultaneously, connected to different Power
Amplifiers.
7. A McIntosh Power Controller may be added to the C2200 to
provide AC Power Switching to components that do not
have Power Control Connections. See your McIntosh
Dealer for additional information.
8. Sound Intensity is measured in units called Decibels and
“dB” is the abbreviation.
9. The PHONO Circuitry uses four Vacuum Tubes. Those tubes
are only Powered-On (glow coming from the tubes) when
the AUX Input is re-titled to PHONO in the Setup Mode.
Refer to page 15 “Re-Titled Inputs” for additional
information.

Technical Description
McIntosh Laboratory, the company who introduced the
world’s first amplifier that could be called “High Fidelity”,
has done it again. The McIntosh engineering staff has created a Tube Preamplifier without compromise, using the
most advanced McIntosh circuit design concepts. Creating a
Preamplifier with this level of performance did not come
easily. Many months of design, testing and measuring were
required. Extensive controlled listening tests, the ultimate
form of measuring, were made before the final design was
accepted.
Input and Output Switching
All signal switching in the C2200 is done by Electro-Magnetic devices. Electro-Magnetic Switching is a proven technology that uses the latest in materials and manufacturing
methods. Each switch consists of a glass tube that is filled
with an inert oxygen-free atmosphere and sealed with tiny
leads protruding from either end. These leads extend into the
tube and overlap one another with a separation of a few
thousandths of an inch. The leads are made from a ferrous
material that is influenced by a magnetic field. They are
first plated with gold as a base material, then with rhodium
and finally ruthenium. Ruthenium is the best contact material known.
The glass assembly is then placed in the center of a multilayer coil of copper wire. The entire assembly is molded
together in a tough shock absorbing material. The switch
and coil connectors extend from the bottom in the form of
printed circuit board terminals. When a DC voltage is applied to the coil, current flows and creates a magnetic field.
The force of the field causes the leads to bend and contact
one another inside the sealed glass tube. The inert gas eliminates corrosion of the contacts and insures a low resistance,
distortion free switch.
All inputs, outputs, and data ports are controlled by
logic circuits in the C2200. The logic is changed by Front
Panel Push-buttons or by a microprocessor IR decoder. This
microprocessor IR decoder is programmed with exclusive
McIntosh software. It receives data from the Front Panel or
Keypad/Sensors and provides the command signals for input switching, data switching, and volume control.
Phono Circuitry
The PHONO amplifier uses 12AX7 tubes. Its input stage
has been optimized for low noise and low distortion performance. Open loop gain of this circuit is 10,000. With high
open loop gain, a large amount of negative feedback can be
used around the phono amplifier to further reduce noise and
24
Top Inside View of the C2200
distortion. The feedback network also provides precision
RIAA frequency compensation.
Input sensitivity of the phono amplifier is 4.4 millivolts.
The gain of the amplifier is 40dB at 1000Hz. The phono
amplifier has a very wide dynamic range. At 1000Hz, the
phono input circuit will accept 50 millivolts without overload, a voltage far greater than the output of any current
magnetic phono cartridge. Therefore, phono input overload
is virtually impossible. A signal level of 10 millivolts at the
phono input at 1000Hz will produce 1 volt at the TAPE output. This output has a source impedance of 500 ohms unbalanced.
Tone Control Circuitry
The TONE control section uses 12AX7 amplifiers. The amplifier stages have been optimized for low noise and minimum distortion. Other electrical circuits are arranged in a
configuration that is the equivalent of a series turned circuit.
A control potentiometer inserts this series tuned circuit into
either the feedback or input section of the tone amplifier.
This provides a 12dB boost or cut at the frequency of the
tuned circuit. The overall gain of the stage is 0dB when the
potentiometer is at its center detent position. A TONE BYPASS Switch is provided to remove all tone control circuits
from the signal path.
Volume Control Circuitry
The VOLUME Control for the C2200 is a very special “Hi
Tech” circuit. It employs a Microprocessor Controlled
Technical Description
Logarithmic Attenuator. There are stringent requirements
for the Volume Attenuator in this design. The channel to
channel tracking accuracy must be maintained. After a great
deal of research we found that mechanical potentiometers
cannot approach the tracking accuracy that McIntosh felt
was necessary. Therefore, we choose to use a dual attenuator with switching driven from a 16-bit serial data word.
Resistor values are decoded by an internal multiplexer to
steps of 0.5dB. Total attenuator range is 107dB. Step error
and channel matching is less than .1dB. THD+N is typically
less than .001% and dynamic range is 120dB. A second
stage is added to the volume attenuator. It controls the gain
of the output amplifier. Its steps are interlaced with the main
section in such a manner that it reduces the output amplifier
gain to unity almost immediately as volume is reduced.
Therefore, noise and distortion generated in earlier stages is
not amplified and low level S/N is dramatically improved. It
is comparable to having a straight wire between the input
switching and output connector. Care has been taken to insure that there are no audible artifacts in the analog output
signal during volume control changes. There is a zero
Bottom Inside View of the C2200
crossing detector built in and all changes in level occur at
the signal zero crossing.
Overall Design
The C2200 was designed to use the best components available. All resistors are the lowest noise 1% metal film. Each
amplifier section has its own power supply filter. The
C2200 is truly worthy of being considered a companion and
peer of the world famous MC2000 and MC2102 Tube
Power Amplifiers.
